Definitions

  • the invention relates to a method for cooling gases with constituents that tend to cake during the cooling process by heat exchange with an evaporating coolant and an intermediate carrier medium guided in annular spaces between the gases and the coolant, the annular spaces being formed by double tubes which are located within a the jacket containing coolant are arranged and on a heat exchanger in particular for performing such a method.
  • the gases to be cooled of the type mentioned above separate their constituents, which liquefy or solidify during the cooling process, on the cooling surfaces.
  • the gas-side surface temperature of the pipes is close to the evaporating temperature of the cooling medium, i. H. it is relatively low.
  • the resulting deposits of the separated components of the gas become very strong after a short period of operation, significantly deteriorate the heat transfer and cause an increase in the pressure loss of the gas.
  • a heat exchanger is known in which the generic method can be carried out.
  • the disadvantages mentioned are avoided by introducing a colder, admixture-free, so-called tempering gas into the annular spaces formed by the gas passage tubes and the coolant tubes and mixing them with the gas to be cooled by vortex formation.
  • This heat exchanger requires that Provision of a specially cooled, admixture-free temperature control gas. It also results that the correct mixture of gas and temperature control gas is difficult to achieve and control in operational terms and requires an increased technical outlay and that the amount of gas increases by the amount of temperature control gas.
  • DE-OS 31 36 860 describes a heat exchanger for cooling hot gases with constituents which precipitate during the cooling process and which has double tubes and coolant collecting chambers formed between two tube plates. Water is passed through the annular spaces of the double pipes, so that, for example, coke forms on the inner wall of the pipes carrying the gas due to the prevailing surface temperatures. From time to time, these precipitates are removed mechanically or by incineration.
  • the double tubes are arranged within an open jacket that contains no coolant.
  • the invention has for its object to improve the known method and the known heat exchanger for cooling gases with components that tend to caking during the cooling process in such a way that with considerably less technical effort and without the need to provide a special temperature gas as well as monitoring and Regulation of its mixture with the gas to be cooled, the disadvantages and difficulties mentioned above can be avoided.
  • the tube bundle heat exchanger with a vertical arrangement of the tubes has an upper tube plate 1 and a lower tube plate 2, into which gas passage tubes 3 open.
  • the gas to be cooled flows from a gas inlet chamber 15 in the direction of the arrows through the gas passage pipes 3 into a gas outlet chamber 4.
  • a connecting chamber 5 or 6 is formed, which on the one hand by the respective tube sheet 2 or 1 and is delimited by a further tube sheet 7 or 8 arranged at a distance from them.
  • the coolant tubes 9 are located in a jacket space 11 which is delimited by a jacket 10.
  • the jacket 10 stands on the tube sheet 7, is sealed against it and ends at the tube sheet 8.
  • the jacket 10 has an inlet connector 12 for a liquid coolant and an outlet 14.
  • a passage tube 13 projects into the jacket space 11 and connects the jacket space 11 to the lower connecting chamber 5.
  • one end of the passage tube 13 is inserted into the lower tube sheet 7.
  • the opening at the other end of the passage tube 13 is located below the tube plate 8 delimiting the upper connecting chamber 6.
  • a liquid level 16 is maintained within the jacket space 11, which is below the upper opening of the passage tube 13.
  • the liquid cooling medium introduced is heated and the saturated steam generated flows in the direction of the drawing arrows up.
  • the saturated steam is then guided downward into the connecting chamber 5 in the through-pipe 13 and flows out of the latter into the connecting chamber 6 and from there into the outlet 14, which here encloses the gas outlet chamber 4 in the form of an annular jacket space. Since the steam absorbs heat from the hot gas to be cooled as it flows through the ring cross sections within the coolant tubes 9, it gets into an overheated state.
  • the outlet temperature of the steam can be determined. It is possible to monitor the level of the liquid in the jacket space 11 by means of a control device (not shown) or to regulate it in the sense of the above control option.
